SPECIFICATION forming part of Letters Patent No. 367,441, dated August2, 1887,

Application filed July 16, 1885.

To all whom it may concern.-

Be it known that I, WILLIAMM. PIATT, a citizen of the United States, anda resident of Macocheek, in the county of Logan and State of Ohio, haveinvented a new and useful Grain- Binder, of which the following is aspecification.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which Figure1 is a perspective View of my improved grain binder. Fig. 2 is a planview of the binder portion of the machine, the head of the standardbeing omitted. Fig. 3 is an elevation, partly in section, from the grainside of the machine. tion partly in section. Fig. 5 is a bottom view ofthe binder portion. Fig. 6 is a perspective view of the reel. Fig. 7 isa perspective view of the reel, showing a modification.

Fig. 11 is a perspective view of the notched plates. Fig.12 is aperspective view ofthe combined retainer and cutter. Fig. 13 is aperspective view of the latch. Fig. 14 is a side elevation of the outerend of the reel shown in Fig. 7. Fig. 15 is an end elevation of thesame. Fig. 16 is a vertical longitudinal section of the inner end of thereel. Fig. 17 is a vertical longitudinal section of the inner end of thereel shown in Fig. 6. Fig. 18 is a perspective view showing amodification in the means for hinging the bats to the arms of the reel.Fig. 19 is a perspective view showing still another modification in themeans for hinging the bats to the arms of the reel. Fig. 20 is a sectionshowinganother view of the same.

A is the apron, B-thc finger-bar, and C the binder-table.

D is the binder-standard rigidly secured to the table, provided with anarm, D, and head D. To the apron side of the head is secured a bracket,L, and secured on the table is a short standard, L. V

E is a shaft-journal in the short standard and in the bracket, havingpulleys or rollers H on opposite sides of the bracket, and carry- Fig. 4is a rear eleva- Serial No. 171,809. (No model.)

ing the outer portions of the belts F, having teeth G for moving thegrain on the table.

M is a vertical bar sliding in the head of the standard, surrounded by aspring, 1 supporting it in its normal position. 0n the lower end of thebar are supported,by means of a rod, K,- the trip-arms I, which areformed with projections z, and are hinged to the shaft E at their outerends. The inner ends of these arms support a short shaft, M, on whichare mounted the forward rollers or pulleys, H, on opposite sides of thebracket L, carrying the inner portions of the belts F. The teeth G arehinged to the belts, and have arms G bearing on the side projection ofthe trip-arms I, retaining the teeth in a position perpendicular to thebelts, except when delivering the grain to the trip-arms. At this pointthe arms G pass beyond the projections, and are permitted to trip andcause the teeth to pass up in a vertical position. Upon the arms comingagain in contact with the projections they assume their normalpositions. D of the standard is a post, 0, in which is pivoted abell-crank lever, N, whose long arm connects with the bar M, and whoseshort arm connects with a rod, P, extending to a movable clntchlialf, Q,engaging withafixed clutchhalf, R, on the shaft S, mounted in the arm DTo the stubble side of the standard D is rigidly secured a bracket, D,and to the same inner side of the head D is secured a bifurcatedbracket, L. J ournaled in these brackets isa shaft, V, geared to theshaft S by cog-wheels T U. In the outer arms of the bracket L isjournaledashort shaft, V On the shafts V and V, on opposite sides of thebracket L, are pulleys or rollers X, carrying the belts WV,which haveteeth Z for discharging the bound sheaf onto the delivery-belt G, havingteeth Gfland working over rollers F.

I Sliding vertically within the head D is a needle-bar, A, provided witha needle, B, having a recess or notch, G, which permits a rotating hook,T, journaled in bearings 'I. T" beneath the table, to pass between theneedle and the twine or cord. Projecting through the front of the headis a takeup, E, and secured to the front of the head is a tension-wheel,D.

Within the standard D on the shaft S is secured a bevel gear-wheel, I,meshing with an- On the arm other bevel gear-wheel, H on a verticalshaft, K. Within the head D on the shaft S is a crank-wheel, D having awrist-pin, I), ongaging the slot in cam Efiseeured to the needlebar.Beneath the binding-table on the lower end 0f the shaft K is secured acrankarm, K having wrist-pin K, to which is connected a pitman, M

M is a slide working in ways M, formed with a horizontal portion havingarack, M, and with a vertical portion having a rack, lil To this slidethe pitman M" is connected. The twine-hook T has a pinion, S, meshingwith the rack M and U is the knotter, journaled in ahanger, V havingpinion X meshing with the rack M a Secured beneath the table platesP,hav

ing notches for the passage of the cord. Between these plates is hingeda retainer, Q, adapted to bind on the cord for holding the outer endthereof. On the outer side-of these plates, and hinged to the same pivotas the re tainer, is a cutter, P, for severing the cord when the knot isformed. The plates P form a support for the twine delivered to theknotter by the hook. The knotter operates to tie the knot in the twineoutside these plates, through which it rotates.

N isapivoted wedge-shaped latch or piece, that passes under thetwinecutter P and retainer Q to raise them out of the way of the twineor cord. The latch is kept in position by aspring, Y, and is formed withan incline, N so that as the frontlower ends of the cutter and retainerslide upward on the incline the upper ends of the cutter and retainerare thrown back and the twine or cord is carried in front of them. Asthe latch passes from under the retainer and cutter, aspring, B, securedto the outer ends of the retainer and cutter, forces them forward,cutting the string or cord, and retaining the end nearest to the needle.The knotter U has a finger, V, pivoted at V.

Referring to the reel shown in Figs. 1, 4, 7, 14,15, and 16, e is thereel-shaft, having boxes at at its outer ends, secured perpendicularlythereto. In these boxes I mount the arms (1, (to which are connected thebats 0,) so as to be readily revolved therein. The inner ends of thearms are provided with cranks p, connected by rods 71 to the head Z of asliding sleeve, Z, having pinand-slot connection with the shaft.

Referring to the reel shown in Figs. 6 and 17, a is the outer head ofthe reel, having sockets a and arms d, and fastened rigidly to therevolving shaft 6. b is the inner head of the reel, mounted so as toturn on the shaft e, having sockets b" and arms d. c are bats secured tothe arms cl. In Fig. 18 I showabat, 0, connected to the arm 52 at oneend by a butt or common leaf hinge, d and in Figs. 19 and 20 I show thebat connected to the arm (1 at the other end by knuckle-jointorinterlocked eyebolts (1. The inner head hasa ring, b,provided withsockets b", said ring being rigidly secured to its arms and formed witha rack-segment, f. g is a shaft passing through the shaft 6 transverselythereof, and having a pinion, t, at one end, meshing with therack-segment, and an arm or crank, h, at the other end, with whichconnects a rod, 7c, secured to the head Z of a sliding sleeve, Z, havingpin and slot connection with the shaft on which it slides, and a flangeor rim, m. g is an upright stanchion secured rigidly to the binderplatform, to which is adjustably connected the reel-standard q, having ajournal-box, 1', at top, which supports the shaft 0. To the standard g,beneath the box, is secured an upper bracket, 8 having rack-segment m,and a lower bracket, 3, having short shaft n, supporting a lever, w,having ajaw, 2, at its upper end engaging the rim or flange, and at itslower end a suitable handle. Beneath the pivot 12 on the lever 20 aresecured the lugs 10, to which is hinged an auxiliary lever, or, whoseupper end engages the teeth of the rack-segment x, for holding thesleeves to desired position, and at its lower end is provided with ahandle. The lower end of the lever w is pressed outward and its upperend inward, accordingly, by a spring, q". 10'' is a spring for holdingthe auxiliary lever in engagement with the rack 00.

The operation of the binder is as follows: The reels feed the grain tothe apron A asitis out by the knives B, and the apron carries the grainto the edge of the table 0, where it is taken by the fingers G on thebelt F and fed under trip-arms or packers I and against the twine, whichcomes up from the retainer Q through the needle-eye to the spool, thetwine yielding to the desired position from the retainer to the upperposition of the needle. As the grain accumulates under the, trip-arms I,it raises them gradually, making room for more grain until'sufficienthas accumulated for a sheaf. As the arms I, which are attached to avertical bar, rise, the bar is raised. As the bar M rises, thebell-crank lever N is turned on its pivot, advancing the rod 1 until,at'the moment enough grain has been received to form a sheaf, theclutelrhalf B is thrown in connection with the clutch-half Q, operatingthe shaft S and the needle-bar, causing the needle to descend. As theshaft Srevolves,the gear-wheels H and I revolve shaft K, and, throughcrank K and rod M", move the slide M back and forth, operating throughracks M and M pinions S and X, respectively, causing the point of thetwine-hook to pass through the cutaway part 0 of the needle between thetwine and the needle and present the twine to the knotter, which ties itin the usual manner. (The form of knotter which I use is that known asthe Behel, patented February 16, ISGA NO. 41,661, though any form can beused.) By the shape of my cam e my needle B is caused to remain at itslowest point until the hook and knotter have performed their functions.As the knotter completes its work,the latch N passes from under thetwine cutter and retainer, and the spring R forces them forward, cuttingthe twine next to the sheaf and retaining the end next the needle.

On the clutch-half It on the shaft S is a gearwheel, T, which engageswith a similar wheel, U, on the shaft V. As the shaft S is caused torevolve, the wheel T revolves wheel U and shaft V, and through themoperates the discharging-belts, the arms Z of which engage with thebundle in their revolution and force it from under arms I, carrying itonto the spiked delivering-belts G, which carry it to the rear intostubble. As the bundle is discharged from under the arms I,they areforced down by spring 1 to their first position, and the lever N ismoved so as to uncouple the clutch and arrest the action of the bindingapparatus proper and discharging-arms, the needle having risen to itshighest position again and stopped. The shafts E and S are run by beltsfrom the main wheel of the reaper, which form no part of my invention.

The operation of my knotting device, in detail, is as follows: Thenormal position of the retainer and cutter is that in which the innerends of these parts are depressed with their operating-faces forcedforward by thespring, the retainer holding the cord which has been laidin the notches of the plates and the hooks in its forward position. Theneedle, havingdeseended to the proper point, is caused to remainstationary by the shape of the cam E in the head of the machine. As theneedle reaches this point, the slide M, carrying the racks M M isadvanced. In its forward movement the rack M engages with the pinion S,and turns the hook T backward. The slide Mis then retracted, and therack M engages the pinion S, turning the hook T forward, the pointpassing through the slot G between the needle and twine and carrying thetwine across the path of the knotter over the notches, (and in front ofthe knife and retaineig) which at that moment is actuated by the pinionX coming in contact with rack M and the knot tied. The continuedmovement of the slide brings the spring-latch under the retainer andcutter, releasing the end last retained and setting the cutter by theact of raising the inner ends ofthe retainer and cutter. As the knot iscompleted, the slide commences its return move ment, the spring-latchpiece N passes to the rear of the pivoted knife P and retainer Q, andspring It brings them to their former position,cntting the twine betweenthe sheaf and the needle and retaining the end next the needle.

To render the operation more clear,it may be stated that the needledescends with-the At this its respective rack, and the revolution of theknotterhook makes the knot. The discharge of the gavel pulls the-loopoff the knotterhook, and the needle at this point arrives at its stationof rest.

\Vhen the needle is down to its lowest extremity,the gripper and cutterplates lie immediately between the knotter-hook and the needle-point andunder the circle traversed by the guidehook T',so that the hook Tperforms a double officethat is, to present the cord to the gripper andto the knotter-hook also and to hold the cord in place while being actedupon by the gripper and knotte'r,respectively. The shape of the slotinthe hinding-table agrees with the delivery of the cord to theknottcr-hook.
